Applications like high-energy attosecond pulse generation, generation of high harmonics from solid targets, and laser electron acceleration all benefit from few-cycle pulse durations and excellent pulse contrast while requiring multi-millijoule pulse energy. Our most powerful high energy OPCPA systems are scalable to multi-TW peak powers at kHz repetition rates while maintaining few-cycle pulse durations. They fit the most demanding requirements while providing stability and reliability unprecedented for systems of this scale.
- Cost- and size-effective highly-stable multi-TW source.
- Cutting-edge combination of peak and average power.
The LIGHT CONVERSION and EKSPLA consortium have built the SYLOS laser system at the ELI-ALPS facility. To our knowledge, the SYLOS laser system at 1 kHz repetition rate generated four times higher peak power pulses compared to the state-of-the-art systems at that time.
The SYLOS laser system is based on LIGHT CONVERSION’s optical parametric chirped-pulse amplifiers (OPCPAs) driven by our PHAROS femtosecond laser and EKSPLA’s picosecond laser. PHAROS pumps two femtosecond OPAs. The first OPA produces passively CEP stabilized pulse at 1.3 µm, which is used for generation of CEP-stable white-light continuum (WLC). At the same time, the second OPA amplifies the WLC in the 700 – 1000 nm spectral range, providing high-contrast seed pulse for the subsequent OPCPA stages. The pulse, amplified to 50 mJ pulse energy at 850 nm central wavelength, is compressed in a sequence of glass blocks and chirped mirrors down to 10 fs pulse duration.
